Transcript of Contextual Interference

Random Practice Practice schedule in which different skills are rehearsed in an unpredictable trial-trial order. Blocked Practice Practice schedule in which the same skill is rehearsed in repetitive fashion. Contextual Interference The degree of interruptions created by the ordering of skills within a practice session. Elaboration Hypothesis Random practice promotes a better appreciation of the distinctive features among skills, resulting in stronger memories and better learning. Action Plan Reconstruction Hypothesis Contextual Interference Effect When comparing the effects of random and blocked practice schedules on the learning of different skills, although blocked practice produces better performance during the practice phase, but when comparing their performance on a later retention test, random practice produces better learning the blocked practice. Shanei CampbellTaylor FongDustin Leong Contextual Interference Give an Example of Blocked Practice Give an example of Random Practice What type of practice would you use as a coach/teacher/therapist in conducting a practice/teaching/rehab program?

Why? During random practice, learners continuously forget and must reconstruct the action plan for each skill each time it is practiced, enhancing learning by leading to the development of a stronger memory representation.
